Lubricity

The term lubricity is often defined as the ability of a lubricant—in this case diesel fuel—to minimize friction between and damage to surfaces in relative motion under load. Generally, the tests used to evaluate diesel fuel lubricity try to create conditions of boundary lubrication. More specifically, test results that quantify a fuel’s lubricity are a measure of the fuel’s ability to minimize friction between and/or damage to surfaces in relative motion under boundary lubrication conditions.

All diesel samples taken by SGS WWFS between 2015 and 2020, fulfill the British BS EN 590 lubricity limit of max 460 µm. Biodiesel blending improves lubricity as well.
